Application led October 22,

. it is moved.

Another object of the invention is to provide a sash holding device which is hidden from view and which may be installed without making any changes in the construction of the window frame, as is necessary in the use of weight devices which are attached by cords which pass into the interior of the window frame over supporting pulleys.

llChe invent-ion broadly contemplates the provision of one or more 'friction plates which are set into recesses in the side edges of the window sash and which are4 normally forced outwardly by springs lying therebe neath into engagement with the adjacent wall of the window frame. The frictional contact between these plates and the window frame wall is sufficient to retain the sash in any position to which it may be moved, but is not great enough to interfere with the movement of the sash to open or closed position.

The invention will be'best understood froma consideration of the following detailed description taken in connection with the acj companying drawing forming part of this specification, with the understanding, however, that the invention is not coniined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications marl: no material departure from the salient features of the invention as expressed in the appended claim.

In the drawing ff Figure 1 is a view of one side edge of a window sash, the central portion ofwhich has been broken away, .showing a pair of holding devices embodying the present inj vent-ion mounted in suitable recesses therein. a suitable recess or pocket 10 to receivethe f `ineral 4:. Y

Referring now-more particularly to, lthe drawing, wherein like numeralsl of reference indicate corresponding parts throughoutfthe several views, the numeral l indicates fgenface .of the o erally a window sash,a portion of one side Y of the adjacent frame showing one of the de- Y vices einbodyingthe invention in operative bar thereof being indicatedby the numeraly `2. ,f Vriheiisual channel iniy which the `sash A.side 1 bai' works is indicated by lthenuineral :3 and a. portion, ofthe frame in which the channel formed is indio The present sash formed transversely of oneend andV disposed jupe-n lone face thereoflwhich is the backzface .of the plate when the saine is in use. This sleeve has one end iiush. with one longitudinal edgevof the plate while the other end terin1- `natcs short of the oppositelongitudinaledge as shown in Figure 3 "and each longitudinal ated generally .by the nul lllCl-Hg ClQYCc-consists of :f anl elongated plate which :has asleeVe edge oftheplate has, afrearwardly extending f iiange 6 and these flanges are connected by a similar flange 6 .which is di'soosed at the end opposite the end upon which the sleeve 6 is formed. It will thus be seen that the longitudinal iiange 6 is separated at one end from? the adjacentend of the sleeve 'forming the space .7. Disposed transversely oftheybacl; face of the plater is alcoil spring 7 which is of a length less than the'width of the plate so that it will fit between the longitudinal 90. Y

flanges 6. The ends of these coil springs are i extended in opposite directions as indicated at 8, the extensions terminating in inwardly directed arms 9 one of which, as shown, M-

tendsinto the sleeve 6 .from the end adjacent plate 5, and the bottom of this pocket has formed transversely thereof and substantially soY midway between its ends the groove 11 for the reception of the coil spring 7.

From the foregoing, taken in connection with the showing of Figure 2 of the drawing, it will be readily seen that when the sash is in position in thev window frame, the spring 7 through the medium of the extended arms 8 and 9, forces the friction plate out of the recess 10 against the bottom of the channel in which the bar 2 moves and a resi-stance will n Y thus be set up to the free movement of the sash in the frame so that after it has been 1 shifted, itwill be held in a position to which it is moved by the frictional engagement of -the plate, or plates where sev'eral are used Von one sash, with thel adjacent frame.

It will also be apparent from the foregoing that one vor Vmorevof the present devices may be readily attached to a window sash and Y the sash installed in its fra-me without the necessity of making changes which are new necessary where Weight controlling devices 'arel employed.

Having thus 'described the invention, what is 'claimed is Awindow sash holding device, comprising an elongated friction plate lia-ving Ia sleeve formed transversely of one end, -a Coil spring disposed transversely of said plate substantially 'midway between its ends, said spring having its ends extended in opposite directions and longitudinally of the plate and each terminating in lan arm extending transversely v ofthe plate, one of said arms being mounted in lsaid sleeve, said device'beingdesigned to be mounted in one side of ia sash bar and said spring' operating to force the plate outwardly 'for frictional engagement with the adjacent frame.

In testimony whereof I'hereunto aiixiny signature.
